I was refered to Halcon Communications in Downey by a few fellow Jeepers. I bought a Uniden pro 510xl there last week along with antenna, cable, quick disconnect. The prices were a little more then you can buy for on Amazon, but that's fine with me as they were a small local shop and could answer all my questions. You get what you pay for IMO. Only thing they didn't have was the Teraflex mount for the tire carrier so i got that frpm 4Wheel parts. I installed everything, took it back yesterday and they adjusted my antenna with their meter for $15. If you are local and need CB or radio stuff this is a great place.
